PUFFER PACKAGE FOR INSECT POWDER.

Application filed April 18, 1923.

To all whom c't may concern.

Be itknown that I, HUGH PERRY McCon- MICK, a citizen of the United States, residing at Baltimore, State of Maryland, have invented certain new and useful Improvements in Putter Packages for Insect Powder; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is a novel improvement in packages or containers designed for containing insect powders, or the like, which are to be expelled from the package by pressure thereon.

One object of the invention is to provide a novel package which will be normally sealed so that its contents will not spill or be lost in transportation from the manufacturer to the dealers, and yet its outlet can be readily opened when desired, and which package will have resilient or springy top and bottom portions adapted to act somewhat like a bellows, so that the contents of the box can be expelled through the outlet (when the latter is opened) by pressure upon the top and bottom portions, said portions resuming their normal positions when relieved from pressure, without the necessity for any internal springs to keep the top and bottom portions extended when not under pressure.

A further object is to construct the container of two complemental parts which may be readily stamped from sheet metal, or other suitable material and when put together will form a secure tightly sealed package, without the necessity for other fastenings.

A further object is to provide the container with a small disk partially punched out of the side thereof which will not allow the contents to escape from the box until the partly detached disk or punching is detached by pressure of a pin or like small pointed instrument thereon when the user wishes to discharge the contents from the box.

The box is of such form that it can be conveniently held in the hand; and is attractive in appearance, and simple in construction, and I designate it a putter package.

I will explain the invention withreference to the accompanying drawings; which illustrate a container constructed in accordance with the invention; and summarize in the claims the essential features of the invention for which protection is desired.

Serial No. 632,859.

In said drawings:

Fig. 1 is a perspective view of the complete putter package.

Fig. 2 is an enlarged longitudinal section on the line 22 Fig. 1.

Fig. 3 is an enlarged transverse section on the line 33 Fig. 1.

Fig. & is a much enlarged detail section through the body showing the disk partially punched out of the side thereof.

As shown in the drawings the package is composed of two complemental parts, and comprises a body member 1 and a corresponding top member 2.

The body member 1 is preferably approximately triangular in plan, the sides of the triangle being much longer than the base, and the points of the triangle rounded. In the bottom of the body 1 is formed a circumferential bead 1 adjacent the lower edges of the body; and the portion 1" of the bottom surrounded by this field is concavoconvex, as shown in Figs. 2 and 3, being convex on its outer side and concave on its inner side. The head 1 preferably lies in a plane slightly above the plane of the lower outer edges 1 of the body, as indicated in Figs. 2 and 3. These lower outer edges are rounded as shown, and connect the bottom of the body 1 with the vertical side portion 1 thereof.

The. body 1 may be of any desired depth, and the side portion 1 thereof is formed with a circumferential concavo-convex head 1, the convex side of the bead being outermost.

The body portion 1 of the package is preferably pressed out of thin sheet metal and the corner portions 1, bead i and bead 1 make it very stiff and rigid, while of very thin material, and at the same time the major portion 1" of the bottom of the box can be readily flexed inward under pressure, but it will automatically resume the form shown in the drawings when released.

The top member 2 of the box is made like the body member, and has a bead 2 in its top portion near the outer margin thereof, and below the plane of its corners 2, which are rounded as shown; and the part 2 of the top enclosed within the flange 2" is concavoconvex, the convexed side being outermost and capable of flexure by pressure thereon, but will automatically return to its normal position when released. The side flange 2 of the top member is shorter than the flange 1 of. the body member. The top should be stamped from sheet metal or other suitable material, like the body member, and the top member is so proportioned and shaped relative to the body member that the flange 2 of the body member telescopes the upper portion of the flange 1 of the body member and has a very close fit thereon, this fit being sufiicient in practice to hold the package securely closed until it reaches the consumer, and when the package is being used by the consumer in the normal way.

The top and body members should not be assembled until the body member has been filled with the material. Then the top member is placed thereon, and when flange 2 is properly seated against bead 1 a substantially air and water tight joint is formed between them and the package is securely closed. 1 v

In the flange 1'* of the box below the bead 1 is an outlet aperature 1 This aperature is preferably only partially formed as inclicated in Fig. 4 by partly punching a very small disk 1 out of the flange 1 this disk being pressed inwardly as indicated in Fig. 4 (which is greatly magnified) so that the disk 1 is not entirely separated from the metal of the flange 1 but can be readily detached when desired by pressing it inwardly with a pin, or other suitable pointed instrument. l/Vhen this disk 1 is pushed in it unseals the aperture 1 and then the contents of the box can be expelled therethrough, by pressing the top and bottom portions 1*, 2, toward each other. These portions are resilient andcan easily be compressed, and because of the tight fit of the portions of the box when these portions are pressed inwardly the contents of the box will be forcibly expelled through the small aperture 1 (after the latter has been opened,) and as soon as the pressure is released the parts 1 2* spring back to normal positions as indicated in Figs. 2 and 3, without the need of any internal or auxiliary springs. I term the container a puffer package, and the parts 1, 2 form a kind of bellows which will remain normally expanded but can be readily compressed as and when desired to expel the contents from the box.

The package is especially adapted for use with insect powders which when the aperture 1 is opened is dispelled forcibly by compressing the package in the hand. The beads 1 2 impart an ornamental appearance to the package, but are not made simply for ornamentation. They produce the convex surfaces on both top and bottom of the package, so that the least compression on the parts 1", 2*, will force the powder out. If

it were not for these beads 1 2 there would be a tendency of the top and'bottom portions of the package to buckle so that they would not spring out automatically when released. i I i As stated, the top' and bottom members of the package are held tog-ether by friction onaccount of the close fit therebetween and as the exterior surfaces of these members are ordinarily lithographed the oil or ink lithographed surface practically forms an air tight seal between the closely fitting portions 2", 1*, of the top and bottom members when they are fitted together, and no glue or solder need be used.

What I claim is:

1. A puffer package for the purpose specified, comprising a body member and a cor-- responding top member, such members having interengaging side portions, a bead in the side portion of the body member, each member having a bead lying without the plane of its face intermediate and adjacent the side portions thereof and a concavo-convex portion surrounded by said bead; the said concavo-convex portions in the body and top members projecting outwardly in opposite directions, and adapted when compressed to expel the contents from the box, and to assume their normal positions when released, the body member having a disk partlypunched in its side below the bead, no part of the periphery of said disk being entirely severed from the body portion, but being detachable therefrom by pressure.

2. A puffer package comprising a body member having a bead pressed in its bottom portion adjacent the side thereof, and located slightly above the lower edges of the side thereof, and a concavo-convex field portion enclosed within said bead; and a peripheral flange or side surrounding the bottom portion and a head in its side portion above the bottom: and a top member having a bead adjacent its side edges and located in a plane below the top of the side thereof; a concavo-convex portion surrounded by said bead; and a peripheral flange surrounding the top portion adapted to closely telescope the flange of the body memher and form a close seal therewith, the bodv member having a small disk partially punched out of its side flange below the bead, no part of the periphery of said disk being entirely severed fromthe body portion; but beinn detachable therefrom by pressure.

In testimony that I claim theforegoing as my own I affix my signature.

HUGH PERRY MoCORMICK.
